"At first it’s not possible to describe anything beyond a wish or a desire.That’s how it begins, making a film, writing a book, painting a picture, composing a tune, generally creating something.You have a wish.You wish that something might exist, and then you work on it until it does. You want to give something to the world, something truer, more beautiful, more painstaking, more serviceable, or simply something other than what already exists. And right at the start, simultaneous with the wish, you imagine what that “something other” might be like, or at least you see something flash by. And then you set off in the direction of the flash, and you hope you don’t lose your orientation, or forget or betray the wish you had at the beginning."
